the last time I was bitten by that issue, the mount point had to be 
owned by the user (group write access apparently isn't enough).  that's 
a bit of a problem with things like gui mounters and I hope that that 
behaviour will be changed sometime in the future.  at least I can't see 
any security problems with a user being able to mount over a mountpoint 
where he only has group write access.
